| 摘 要： | 针对气象工作需要,提出一种新的适用于多维问题的函数拟合方法。实质上本想法是窗口变换技术和小波分析的"粗化";,因为精细的小波分析在目前尚难用于方程数值解等气象问题。由此可以形式上构成一种分块的Galerkin方法,使大气控制方程求解并行化。

| Abstract: | A new scheme of function fitting suitable for multi-dimensional problems of meteorological nature is proposed.It is in reality a problem of"window"transform and small-wave analysis"being coarse".Fine small-wave analysis remains inaccessible to numerical solutions of an equation in a meteorological context.Through the"being coarse"method it is possible to formally construct a piecewise Galerkin scenario so as to realize the parallel solution of atmospheric governing equations. |
